Well I do know that they have the same atomic number, but they have a different mass number.

Is that what you were looking for?

Nuclear fusion, like the example here, produces huge amounts of energy. Consider the statements below. BUT ONE statement provide

vredina [299]

Answer:

Explanation:

Nuclear fusion of a form of nuclear reaction in which two small atomic nuclei combines to form larger ones with the release of a large amount of energy.

For example;

²₁H + ²₁H → ⁴₂He + Energy

The energy released in a nuclear reaction provides the needed temperature for another set of ²H atoms to fuse. This process in turn yields another ⁴He with the release of a lot of energy. Thus, enormous release of energy accompanies a nuclear reaction.

It is based on this principle that an hydrogen bomb is formed.

How many moles are there in 36.0g of Beryllium

Alja [10]

Answer:

4.00 mol

Explanation:

$\frac{36.0g Be }{1} *\frac{1 mol}{9.0122 g}$ = 3.994585118 mol

(If you round Be mass to 9 you get 4 mol)

A solution is prepared by dissolving 0.5482 grams of iron(III) nitrate in enough water to make 100.0 mL of solution. A 10.00 mL

Kamila [148]

Answer:

$C_2=9.066x10^{-4}M$

Explanation:

Hello,

In this case, the first step is to compute the molarity of the first solution, for which we consider the molar mass of iron (III) nitrate that is 241.86 g/mol to compute the moles in 100.00 mL (0.1 L) of solution:

$M=\frac{0.5482g*\frac{1mol}{241.86 g} }{0.1L}=0.0227 M$

Which is actually the concentration of iron (III) ions. Therefore, for 10.00 mL of such solution, the concentration until a dilution to 250.0 mL results being:

$C_2=\frac{C_1V_1}{V_2} =\frac{0.0227M*10.00mL}{250.0mL} \\\\C_2=9.066x10^{-4}M$
